Bag type dust arrest pole electric dust-collecting device

Abstract

The invention discloses a polar electricity dust removing device with bagged dust collection, which comprises a dust remover shell, a smoke gas inlet, a uniform air board, a smoke gas outlet, dust buckets, filtering bags, electrode wires and a high-voltage insulating compartment, wherein, a plurality of rows of cloth bags are evenly arranged at interval inside the shell, and the high-voltage electrode wires are arranged at the circle center of a concentric circle of every four cloth bags and connected with a power source through the high-voltage insulating compartment arranged at the top of a dust remover; the uniform air board is arranged under a plurality of rows of filtering bags at the lateral wall of the dust remover shell close to the smoke gas inlet, multiple levels of dust buckets are arranged under the multiple rows of filtering bags, and the smoke gas outlet is arranged above the multiple rows of filtering bags at the lateral wall of the dust remover shell. The polar electricity dust removing device with bagged dust collection has the advantages of simple and unique structure, superior technical performance, smaller resistance, effective overcoming of the reverse corona phenomenon and good dust removing effect, etc. The polar electricity dust removing device with bagged dust collection improves the integral dust removing efficiency under the agglomeration action of electrostatic fields and the interception action of the cloth bags, effectively protects the filtering bags from being burned out by discharge sparks by adopting protective cage structure, and reduces device cost by substituting the steel polar plates with the filtering bags.

Description

technical field [0001] The invention relates to a flue gas dedusting device, in particular to a bag-type dust collecting pole electric dedusting device. Background technique [0002] Electrostatic precipitator and bag filter are the two most widely used methods in the field of flue gas particle purification. The electrostatic precipitator has the advantages of a large particle size range and high dust removal efficiency, but there is a reverse corona phenomenon for some coal dust and high-temperature and high-resistance dust, resulting in a decrease in dust removal efficiency; in addition, electrostatic dust removal for fine particles (less than PM2.5) is difficult to effectively remove, and the surface of these fine particles is often enriched with trace heavy metal elements and organic pollutants produced by fuel, which is very harmful to human health and the ecological environment. The emission standard of smoke and dust is raised to 50mg / m 3 Below, the conventional ele...

Problems solved by technology

In short, the electric bag composite dust removal technology is a promising dust removal technology, and great progress has been made in research, but there are obvious problems such as the complex structure of the dust collector, the filter bag is easily damaged by the discharge spark, and all of them use DC power supply , the supply voltage and electric field strength are limited

[0004] With the continuous improvement of national smoke and dust emission standards, the use of a single dust removal technology can no longer meet the purpose of efficient and economical removal
